<p>Reports comparisons with <code>None</code>. That type of comparisons
  should always be done with <code>is</code> or <code>is not</code>, never
  the equality operators.</p>
<p><b>Example:</b></p>
<pre><code>
a = 2


if a == None:
    print("Success")
</code></pre>
<p>Once the quick-fix is applied, the code changes to:</p>
<pre><code>
a = 2


if a is None:
    print("Success")
</code></pre>
